Sons Of Liberty Gun Works M89 Heavy Drive 11 Inch M-LOK Rail with Steel QD Sockets

The Sons Of Liberty Gun Works 11" M89 Heavy Drive M-LOK Rail features the Drivelock design developed with Icon Defense. Three independent wedges interface with angled grooves in a proprietary barrel nut to clamp the rail onto the steel barrel nut, while driving the handguard rearward toward the upper receiver for improved stability.
